我遇到了一个问题,即使我的路由可以连接并向JMS生成消息,但对于JMS运行状况来说,执行器探针仍会失败。简而言之,Actuator表示它已关闭但正在运行。
技术堆栈和技术说明:
org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory
用于连接工厂。我的路线就像筹码一样简单:
<route id="timer-cluster-producer-route">
<from uri="timer:producer-ticker?delay=5000"/>
<setBody>
<groovy>
result = ["Name":"Johnny"]
</groovy>
</setBody>
<marshal>
<json library="Jackson"/>
</marshal>
<to uri="ref:jms-producer-cluster-event" />
</route>
基于XML的Artemis配置
使用Spring-boot支持基于Java的配置时,我正忙于相应地迁移XML bean。因此,我将一个有效的bean.xml文件粘贴到项目中并启动了路由,我可以发送消息并运行状况检查返回OK

春季启动自动(黑色)魔术配置
然后,我使用了application.yaml文件通过使用this method来配置artemis连接,如Spring-boot文档中所述。当我的application.yaml文件包含以下配置时,这也起作用:
artemis:
user: artemis
host: localhost
password: artemis
pool:
max-sessions-per-connection: 500
enabled: true
max-connections: 16
这就像一种魅力。
勇敢尝试Java配置。
所以我接着去淘金,尝试了如下所示的基于Java的配置:
@SpringBootApplication
@ImportResource("classpath:/camel/camel.xml")
public class ClusterProducerApplication {
public static void main(String[] args) {
SpringApplication.run(ClusterProducerApplication.class, args);
}
@Bean
public JmsComponent jms() throws JMSException {
// Create the connectionfactory which will be used to connect to Artemis
ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory();
cf.setBrokerURL("tcp://localhost:61616");
cf.setUser("artemis");
cf.setPassword("artemis");
//Create connection pool using connection factory
PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory();
pooledConnectionFactory.setMaxConnections(2);
pooledConnectionFactory.setConnectionFactory(cf);
//Create configuration which uses connection factory
JmsConfiguration jmsConfiguration = new JmsConfiguration();
jmsConfiguration.setConcurrentConsumers(2);
jmsConfiguration.setArtemisStreamingEnabled(true);
jmsConfiguration.setConnectionFactory(pooledConnectionFactory);
// Create the Camel JMS component and wire it to our Artemis configuration
JmsComponent jms = new JmsComponent();
jms.setConfiguration(jmsConfiguration);
return jms;
}
}
因此,当骆驼启动时,我会在启动时看到以下警告:
020-07-28 12:33:38.631 WARN 25329 --- [)-192.168.1.158] o.s.boot.actuate.jms.JmsHealthIndicator : JMS health check failed
javax.jms.JMSSecurityException: AMQ229031: Unable to validate user from /127.0.0.1:42028. Username: null; SSL certificate subject DN: unavailable
5秒延迟后,计时器开始计时并生成消息。我登录到Artemis控制台,可以浏览消息并看到它们正在创建。但是,当我对执行器的运行状况进行检查时,会看到以下内容:
"jms": {
"status": "DOWN",
"details": {
"error": "javax.jms.JMSSecurityException: AMQ229031: Unable to validate user from /127.0.0.1:42816. Username: null; SSL certificate subject DN: unavailable"
}
},
这对我来说似乎是个很大的错误。
有关连接池实现的观察。
我注意到AMQ连接池已移入以下Maven依赖项:
<dependency>
<groupId>org.messaginghub</groupId>
<artifactId>pooled-jms</artifactId>
</dependency>
我想让我也尝试一下。它显示了与上面概述的行为相同的行为,还有另外一件有趣的事情。在将org.messaginghub.pooled-jms
用作连接池时(也由spring-boot文档推荐),以下内容将在启动时记录。
2020-07-28 12:41:37.255 INFO 26668 --- [ main] o.m.pooled.jms.JmsPoolConnectionFactory : JMS ConnectionFactory on classpath is not a JMS 2.0+ version.
根据the official repo,该连接器符合JMS 2.0标准。
快速摘要: 通过Java配置JMS组件时,执行器似乎没有获取连接工厂的凭据。通过使用spring-boot application.yaml配置,目前可以解决此问题,但它限制了您在Camel上配置JMS客户端的方式。
答案 0 :(得分:0)
因此,在经过一些挖掘并与GitHub上的Spring-boot人员联系后,我发现了问题所在。使用Java配置时,我正在使用连接工厂配置Camel的JMS组件。但是,Spring-boot完全没有意识到这一点,因为它是Camel组件。因此,JMS使用的连接工厂需要暴露于Spring-boot才能正常工作。
修复相对简单。参见下面的代码:
@Configuration
public class ApplicationConfiguration {
private ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory();
@Bean
public JmsComponent jms() throws JMSException {
// Create the connectionfactory which will be used to connect to Artemis
cf.setBrokerURL("tcp://localhost:61616");
cf.setUser("artemis");
cf.setPassword("artemis");
// Setup Connection pooling
PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory();
pooledConnectionFactory.setMaxConnections(2);
pooledConnectionFactory.setConnectionFactory(cf);
JmsConfiguration jmsConfiguration = new JmsConfiguration();
jmsConfiguration.setConcurrentConsumers(2);
jmsConfiguration.setArtemisStreamingEnabled(true);
jmsConfiguration.setConnectionFactory(pooledConnectionFactory);
// Create the Camel JMS component and wire it to our Artemis connectionfactory
JmsComponent jms = new JmsComponent();
jms.setConfiguration(jmsConfiguration);
return jms;
}
/*
This line will expose the connection factory to Spring-boot.
*/
@Bean
public ConnectionFactory jmsConnectionFactory() {
return cf;
}
}
